Since then, the boots have fallen out of favor with the fashionable set. Don't get us wrong, there is truly nothing as comfortable as Ugg boots, but in terms of style, they are lacking. The dull brown hue, often-scuffed exterior and slouchy tops can look sloppy (especially when paired with the aforementioned tracksuit).

The ease of wear is unparalleled. All one needs to do is pull them on and you're dressed and ready to fight the freezing temps (or, if you're in L.A., brave the 60 degree weather. That said, Uggs' casual nature is just that -- casual.

Not ready to give up your Uggs? Don't stress. Here, four guidelines on wearing the furry footwear:

1. Consider the occasion. Uggs are OK for walking around a ski town (though we think L.L.Bean boots are a more stylish -- and waterproof -- option).

3. Uggs are not OK in the office. Would you wear sweatpants to work? No. Then don't wear the sweatpants equivalent for your feet.

4. If you are going to rock your Uggs, please refrain from taking them to the next level of outlandishness. Sequins, sparkles, bright hues and the like should be avoided at all costs.
